Please add nr_ites as a parameter to this function and to
its_add_device, such that this hardcoding can be pushed all the way down
into the final patch which adds the temporary registration code in
xen/arch/arm/platforms/thunderx.c.
+1, I would also add the physical ITS in parameter as it's not possible to
get it based on the devID (see its_get_phys_node).
thunderx.c does not have physical ITS to pass as parameter.
That's not true. You are able to get the PCI root controller which
should have a phandle to the ITS device tree node.
With this dt node in hand you can get the correct physical ITS.
